Programmatically generate video or animated GIF in Python?

by

I’d recommend not using images2gif from visvis because it has problems with PIL/Pillow and is not actively maintained (I should know, because I am the author).

Instead, please use imageio, which was developed to solve this problem and more, and is intended to stay.

Quick and dirty solution:

import imageio
images = []
for filename in filenames:
    images.append(imageio.imread(filename))
imageio.mimsave('/path/to/movie.gif', images)

For longer movies, use the streaming approach:

import imageio
with imageio.get_writer('/path/to/movie.gif', mode="I") as writer:
    for filename in filenames:
        image = imageio.imread(filename)
        writer.append_data(image)
